Statistical bias correction for creating coherent total ...

· A long-term coherent total column ozone (TCO) record is essential to ozone layer variability assessment, especially the detection of early signs of ozone recovery after years of depletion. Because of differences in satellite platforms and instruments design, calibration, and retrieval algorithms, however, significant cross-mission biases are observed between multiple sensor TCO observations in ...

LIDAR Ozone Report

Above 40 km or more, depending on the power of the laser sources, the use of a high number of points introduces a bias in the ozone retrieved quantity. Recent simulations performed in the frame of the NDSC by various lidar teams allowed to quantify this bias for a given configuration. This bias can reach 10% at 45 km (Godin, 1996).

GMD - An intercomparison of tropospheric ozone reanalysis ...

After 2011, no TES tropospheric ozone measurements were assimilated, which could lead to enhanced ozone biases, as demonstrated by Miyazaki et al. (2015). Assimilation of MLS measurements does not noticeably influence the tropospheric ozone analysis in the tropics. In the NH subtropics and tropics regions the reanalyses show some larger deviation against sonde observations at lower altitudes ...
